To all whom t may concern:

Be it known that I, ROBERT A. GALLY, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in vVeb-Guiding Devices, ot which the following is a specification.

In my prior Patent #1,109,578, September 1st, 1914, is shown a floating member adapted to actuate either or two valves set at the two sides of the centering arm of the said iloating member, but normally out of contact therewith', the ports to the shifting mechanism pneumatics being in a iXed seat piece and normally covered by the two valves, the floating memberbeing controlled to central position by two detector fingers engaging the two edges of the music sheet. As in some instances the available space is not as convenient for this form, as is the usual upright player piano, as for a player grand piano with the music rolls positioned in a condensed space near the wrest plank as herein shown, it is then desirable to alter the shape or' the automatic tracking device, as will now be set forth, although the float ing seat and other special features of the present tracking'devices are not limited to grand pianos, but are to be applied wherever desirable. are also shown the yoke :trame of my prior Patent #1,112,061, September 29, 19141, as a convenient means for' its purposes, although other means may be employed for this part of the apparatus.

1n the drawings, Figure 1 is a front view; Fig. 2 a plan of the upperspindies, etc., ot Fig. 1; Fig. 3 a plan View 1i the floating valve seat and the valve levers; and Fig. 1 is a vertical cross section taken on line of Fig. 1, the keys and principal case parts being included, as well as the shitting pneumatics and their connections to the tracking yoke; and Fig. 5 is a larger scale view of the detail of the seat block and one valve therewith as viewed from the right at section line m-m of Fig. 1, the valve being seated, and Fig. 6, the same valve when ott its seat.

Two detector fingers 1, 2, normally contact each edge of a music sheet 3, each detector finger having a vertical main part, each extended down and fixed to its h0ri` TWith the present' improvements zontal arm 1, 5, two pivot bearings, 7, o1I any suitable frictionless. type being pr0 vided, one at. each junction of the vertical arms l, 2, and their horizontal arms 4, 5. Each vertical arm 1 and 2 is fixed to its ceuresponding horizontal arm 41 and 5 by means of bracing, spot welding or riveting, and it is desirable to assist the steadiness of the pivot pins 6 and 7 by inserting them in bushes or hubs 5 7a which are tightly set and riveted into holes through the junctures of the arms 1, 1 and 2, 5. The pivot pins 6 and 7 are journaled in suitable holes or notches in the bearing blocks 6", 7b, right angle clips GC, 7, being now shown as holding the pivot pins and 7 in place in their notches in the bearing blocks 6", 7 b. The two horizontal arms et', 5, extend to# ward each other from their pivots 6, 7, until they nearly moet at the middle point between the two pivots, andeach arm 1, 5,

has a valve part S, 9 positioned directly over corresponding ports 10, 11, in a ioating lock or seat 12. This floating seat 12 is carried at the outhanging part of a horizontal swing-able member lying adjacent to but tree from the valve Varm 5, and this' seat member is pivoted at its fulcrum end of its arm 18 by a pivot la having its axis approximately coincident with that of the pivot 7 of the valve arm 5, the tubes 15, 16 `being fixed to the arm 18 and extender to the seat 12 and leading` to the ports 10, 11, so that the seat 12 and its port 11, and the valve arm 5 will swing in closely similar arcs, and as the distances of' the two ports 10, 11, are equal from their respective pivots 6, 7, and the distances from the' pivots 6, 7 to the contacts of the arms 1, 2 with the edges of the sheet 1 are equal, the motion of the two arms 1, 2, to and from each other from different widths of truly centered sheets, will always `hold the two arms 4, 5 exactly closing the ports 10, 1l of the iloating seat 12 as the said seat is held up against the valve parts f., 9, of those two arms L1, 5 by means of the counterweight 17 on that extension of the arm 13 to the other side of its pivot 1d than the seat 12.

Counterweights 18, 19 at the ends of the arms 1, 5 that are yextended beyond their pivots G, 7, partly counterbalance the weight of the inner ends of the arms 4, 5, and

thereby preventany over heavy pressure of the contact parts of the arms 1, 2 against the edges of the music sheet 3, these weights preferably being ustable along their arms 4, 5. The eounterweight 17 of the seat arm 13 and seat 12 is made adjustable on the outwardly extended partof the arm 13, and is regulated suiliciently heavy so that the seat 12, and ports 10, 11, will always be certain to follow up to the valve parts 8,'

9, but not heavy enough to overcome the weight of either one alone of the arms 4, 5 and their valve parts 3, 9 when the valve part of the other arm is raised trom its port of the seat 12.

lWhen a music sheet 3 is diverted a trifle to the right of its true central line oic travel, it will cause one of the two arms as 5, to lift a shade higher than the other, as 4, at which time the lower positioned valve parts 8 and 9 of the two arms 4 and 5, must have its corresponding port 10 or 11 kept closed to it by the overbalanced weight of the counterweight 17, but the weight oi' the arm 4 whose valve part 8, is then closed to port 10 must be suthcient to prevent any tendency of the weight 17 pressing the seat 12 up so strongly against the closed valve part 8 and its arm 4 as to throw the corresponding contact part of its vertical arm 1 away from its contact with its edge of the music sheet 3, as that would destroy the centralizing reading from the two contact arms 1, 2, both of which must always remain in contact with the edges oi the sheet to insure correct reading to the central line of travel of the sheet. lWhen the music diverges to the left the action of the arms, etc., is the opposite of the foregoing.

When the music sheet 3 is traveling to its true central line of travel, both ports 8, 9, are closed against the valve parts 10, 11 of the arms 4, 5, but whenever thev sheet moves to a slight degree to the right or left from that central travel, both of the contact arms 1, 2, are moved in that one direction, causing the horizontal arm 4 or 5, of that side to which the sheet has moved, to raise its valve parts 8 or 9, away from its corresponding port 10 or 11, while at the same time the other arm 4, 5, has been allowed to drop and press the seat 12 down, thereby doubling the quicknessof opening of the valve part which has started from its seat. Thus a very quick action is secured.

To prevent a fluttering of the shitting parts of the apparatus, it is best to construct the valve parts 8, 9 so that they will have a slight lost motion between the start of that end of anarm 4, 5, away from the seat 12, which is accomplished in the present showing by hinging the valvey parts 8, 9, at their front ends, and bending their rear ends up and over the corresponding overlying parts of the arms 4, 5, the valve parts 8, 9, thus lying horizontally under the end parts of the arms 4, 5, and pressed against the said arms when the ports 10, 11 oi the seat 12 are closed against the said valve parts, as in Fig. 5, and that when either one of the said arms 4, 5, has its distance increased from the seat 12, the corresponding valve part 8 or 9 will'remain resting on the port 10 or 11 until a slight motion ot' the arm 4 or 5, has occurred, when that arm will then contact the upper part of the bend of the valve part and lift that valve part from its port as shown in Fig. 6.

The valve ports 10, 11, lead by the tubes 15, 16 through flexible tubes 20, 21, to the usual pneumatics of valves at 22, 23, said valves being normally inactive, but when one or" these valves is actuated by the opening 01": the corresponding one of the ports 10, 11, said valve 22 or 23 energizes the pneumatic motor 24 or 25, which said motors have suitable connections by wires 26 and 27 to the arm 23 of a vertical rock shaft 29 extended from this pneumatic motor set below the keybed 30 of the casing to the upper arm 31 of this shaft 29 which arm 31 is at a proper position of level with the music roll spindles 32, 33, the shifting of the said spindles 32, 33, being accomplished by these pneumatic motors and connections through a linal connecting rod 34 led from the arm 31 of the vertical shaft 29 to the unitary means or yoke 35, which yoke engages both said spindles 32, 33, and with a spring 35 holds these two spindles toward each other, thus engaging and carrying the music roll 37 on which the music sheet 3 is mounted, but leaving the two spindles 32, 33, and the roll 37 free to be moved lengthwise of the spindles and roll to enable the guidance oit' the music sheet 3 to its central line of travel as detected and determined by the two detector arms 1, 2 contacting the two edges of the sheet and controlling its central travel by means of the various parts already described.

r1`he particular yoke 35 and other shifting parts as shown and described are of the very desirable form of applicantsprior Patent #1,109,573, already mentioned, but other connections and shifting means may be used in their place, or va ious other modifications or equivalents be employed, and yet the present invention be retained; and although for convenience the present sho-wing has been that of an embodiment in a player piano, it is to be understood that theV present invention is not limited to any particular apparatus, but is intended to be used in any apparatus employing a traveling sheet or web; and it is also understood that electric, hydraulic or mechanical equivalents may be substituted for the pneumatic features hereof as may be suitable for any particular use yto be made of this invention.
